Functions

func Jitter

func Jitter(t time.Duration, maxJitterPercent int) (time.Duration, error)

Jitter accepts a Duration and maximum percentage to jitter (as an int), and returns a random Duration in the range t +/- maxJitterPercent.

func JitterRequeue

func JitterRequeue(defaultDuration time.Duration, maxJitterPercent int, log logr.Logger) reconcile.Result

JitterRequeue accepts a default requeue time, a maximum percentage to jitter, and a logger, and returns a Result containing a requeue time which has been randomized with jitter.

Types

type ClientHelper

type ClientHelper struct {
	client.Client
}

func (*ClientHelper) CreateOrUpdate

func (r *ClientHelper) CreateOrUpdate(ctx context.Context, obj client.Object) (string, error)

CreateOrUpdate attempts first to patch the object given but if an IsNotFound error is returned it instead creates the resource.
